there may be a mistake in my answer
Answer:
b
Step-by-step explanation:
Answer:
the answer is "d" because the x region is negative 2 and the y region is a positive1
Area of rectangle=> L•l= 8•5= 40 in²
Area of the triangle=> (b•h)/2= (8•3)/2= 24/2= 12 in²
Area of the shadowed surface is 40-12= 28 in²
The second answer 5(2,5d)
